The Phoenix Police Department -- headed by a former Dallas assistant police chief -- has started a review of the last five years of police shootings, the Arizona Republic reports.

The newspaper reports that the review is meant to examine the factors that led to officers pulling the trigger, but could also help ward off Justice Department scrutiny. Some in Dallas have also called for the federal department to look into police shootings here.

Phoenix's police chief is Danny Garcia, who was a candidate for the Dallas top cop job the eventually went to David Brown. Garcia is quoted as saying the review "is critically important for us because it can save our officers' lives and citizens' lives."
